What is this site?
This site is meant to help spread the vedanga of jyotish (vedic knowledge). With that goal in mind, the web software:
- works on mobile, tablet, and desktop
- can create, save, and share birth charts / kundalini
- calculates multiple vargas and dasas
- search, share, modify, and save public charts
- various panchang calendars (days from sankranti and purnanta masa from visnu)
- prasna and chart views - the clock icon (underneath the month to the right of the lat/long) or any of the times listed will open up a chart of the time
- geolocation - the location pin icon will find your location anywhere in the world (underneath the month to the left of the lat/long.)
- can search for muhurta
None of this would be possible without the support of the parampara. Special thanks to Pt. Sanjay Rath, Visti Larsen, and Freedom Cole and many others.
What are the latest changes?
The latest changes are available here
When are you going to build X?
The current roadmap is here.
Is there an app? How do I access this on mobile?
Just open up https://deva.guru in your mobile browser. The app is still being tested.
How do I contact you?
Send an email to tj at deva guru or join the telegram chat.
How long does it take to respond to an email?
So far, I’ve responded to all email in 48 hours. If you haven’t heard back, check your junk mail or spam folder.
How stable is the software?
The software has been used for professional services since roughly mid-2020.
Are there bugs?
I’m not Ganesh, so yes, there will be bugs.
How do I report a bug?
If something doesn’t work properly, please send an email
What browsers are supported?
Firefox 75+, IE Edge, Chrome for Android 80+, and IOS Safari (13.0+) seem to work reasonably well.
Safari for desktop does not support some modern components. Please use Firefox or Chrome.
What is muhurta search?
A muhurta is a time to begin an activity. If you are looking for a particular time, the muhurta search can help you locate the exact positions you are looking for instead of having to search for them manually. This simplifies finding optimal muhurtas for ceremonies, griha pravesh, etc.
How accurate is the panchang?
The monthly panchang has to calculate hundreds of values and is using approximate values accurate to a within a minute. If you need the exact timings, you must click through to the full chart.
- muhurta search doesn’t work on touch devices. The original code was written in 2010 and needs to be updated to support modern browsers.
How do I change the chart style?
Next to each chart simply click on the
How do I share my chart with someone?
How many cities are supported?
How can I see 4 chakras on my laptop?
You can change the number the chakras by adjusting the zoom level on your browser. For Firefox and Chrome, you can do this by pressing “Ctrl” key and “+” or “-“. In Safari, this would be the “Command” key and “+” or “-“.
What does alpha/beta mean?
Any item marked as beta has been tested, however, may need some changes in the future in either the options or calculations. Please report any errors.
Any item marked with alpha means that no tests have been written and the calculations have not been verified. Use at your own risk.
Will you open source this software?
Not at this time.
Where are my Jagannath Hora files on Windows 10?
Usually, the Jagannath Hora files C:\Program Files x86\Jagannath Hora\data. However, sometimes you need to check a different directory to find your data. First, you may need to allow yourself to see the hidden folders in windows explorer. After that, you would be able to find your data at: “This PC” -> “C:” -> “Users” -> Your username directory -> “AppData” -> “Local” -> “VirtualStore” -> “Program Files(x86)” -> “Jagannath Hora” -> “data”
What ayanamsa are you using?
Will you support multiple ayanamsas?
There is potential to support multiple ayanamsas, but it may cause too much confusion. In any ayanamsa, what is important is the rectification of the chart and having accurate degrees for the lagna and the moon, which are the fastest moving bodies. If someone shares a chart that was rectified and whoever opens it is using a different ayanamsa, they may be seeing an incorrect chart. If there are multiple ayanamsas supported, on each share everyone would have to manually verify the position of lagna and moon.
How are positions calculated?
The position of the graha are calculated with the lahiri-chitrapaksa ayanamsa and from the apparent positions from the center of the earth. The apparent position accounts for the time that light takes to travel from the planetary body to earth.
What is combustion?
Combustion is an astronomical phenomenon that occurs when a graha is no longer visible in the night sky when it is too close to the sun. This information is given in chapter 9 of Surya Siddhanta and can differ based on the forward or retrograde motion.
How do you calculate the hora lord?
There are actually three different ways of calculating the hora lord each used for different purposes based on whether it depends on sunrise and sunset.
- Depends on sunrise only. Since this does not depend on the sunset, it starts from sunrise and proceeds in 60 minute increments.
- Depends on sunrise and sunset. Since this depends on both sunrise and sunset, the hora will have not have fixed length. Sunrise to sunset will have one length, while sunset to sunrise have another. The hora will start with sunrise.
- Depends on neither sunrise or sunset. This starts at 6am and increments every 60 minutes.
The hora lord is based on the number of hours passed from sunrise starting from the vara lord and proceeding with the graha in order of descending velocity. The hours are fixed at 60 minutes and do not depend on sunset.
Some other apps use calculation 2 for the panchang while this site uses calculation 1.
What is the kala hora?
Hora can also be without reference to sunrise and sunset. This hora calculation takes sunrise to be fixed at 6 am. However, there are two additional ways in which this can be calculated.
- We can use “local standard time” (LST) which ascribes 6 am to be based on the timezone and various daylight savings adjustments.
- We can also use “local noon” (LN) where we calculate 6 am based on local noon.
The author prefers to use the local noon calculation.
How do you calculate the kala?
The kala chakra order is su, ma, jp, me, ve, sa, mo, ra There are 8 in the day and 8 in the night. The time period for the day kalas are (sunrise - sunset) / 8 and the time period for the night kalas are (sunset - next_sunrise) / 8 The kalas of the day start from the vara lord. The kalas of the night start from the 5th from the vara lord. Both day and night proceed clockwise around the kala chakra.
Why is the date range only from 1700-2100?
Both the Julian and Gregorian calendar have been in use before this time. As different countries adopted the Gregorian calendar at different times, it’s difficult to determine the correct calendar to use earlier than 1700. This may eventually be implemented for research purposes by allowing the date to be in julian days.
Why are the amsa devata different than my other software/books?
This software is using the names given by the sanksrit shlokas rather than the names given by the translated versions. For instance, in the D60 devata, the 39th is listed as “pūrṇa-candra”. However, in the shloka itself, it is called “pūrṇa-niśākara” (this is true in both the Sharma and Santhanam translations). Sometimes the translation gives the name “surya”, however, the shloka gives the name “arka” which is another name of surya. If you think there’s an error in the direct transliteration of the names from the shlokas, please let me know.
What are the alternate arudhas?
The main arudhas are given by the reflection of the lord of the sign. The alternate arudhas are given generally by the nodes and are marked with an underline. For instance, vrichika and kumbha have two lords each. The alternate arudhas given by Ra and Ke are marked with an underline. There’s also another additional option for giving the arudhas from the mulatrikona lord for vrshabha, kanya, and mina. Since these are Mo, Ra, and Ke respectively, we mark all of these with an underline also.
Payment and Billing Questions
Is there a free trial?
Yes, there is an 18-day free trial. During the trial, you will see “Trial Account” in the top right and the number of days remaining on the accounts page. After the trial is over, you may continue to use the site with the Kāla Edition or upgrade to a paid version.
Do you offer any annual discounts, promotions, or sales?
Our policy is to be like Surya and that means to be as consistent as possible. Everyone should know what to expect. Surya is the destroyer of rajas and we do not want any rajas or tamas to influence the software in any way. This includes having a marketplace, promotions, discounts†, sales, bulk sales, advertising, or upselling which would result in undue influence or thinking on the lines of Buddha.
Thinking about money changes our gunas and then we can’t really focus on jyotish. So we’ve made it super-easy to join, upgrade, downgrade, or cancel. We need to keep our thinking on money to an absolute minimum. We need to keep our focus on Surya as we need the sattva and the pure agni for jyotish, otherwise, who knows what this software will turn into.
† We do give discounts to sanyasi or those who live in ashrams as that is the appropriate action
What payments do you accept?
Our payment provider, Paddle, currently accepts Paypal and credit card.
How easy is it to upgrade, downgrade, or cancel?
We’ve tried to make this as easy as possible.
After you’ve subscribed, on the account page you will see two buttons:
- Change plan
- Edit/cancel payment
If you are upgrading, there will be an immediate charge which is pro-rated against your current plan. Your new billing cycle starts on the day of upgrade.
If you are downgrading, there will be a credit and your following payments will be $0 until the balance of your credit has been used.
If you cancel the service before the end of your current paid up period, your cancellation will take effect at the end of the current billing cycle, and you will not be charged again.
In addition, you can request a refund of the unused prorated portion within 30 days of the transaction.
What happens to my data if I downgrade or cancel?
Under no circumstances, will your data be lost.
If you are a subscriber, no data will be deleted unless you delete it yourself. However, features and data access will be limited by the plan you’ve chosen.
If you have cancelled your account and it hasn’t been used for 2 years, we’ll send you a backup your data and ask if you would like to delete your account. If there is still no usage after a year, your account may be scheduled for deletion. If you choose to rejoin, you can re-import the backup.
There’s an import, but can I export my data?
There is no official export function at the moment, but if you contact us, we can export your data.

Will you sell my information?
What is a panchang?
A panchang is an Indian calendar which has traditional units of timekeeping based on the position of both the sun and moon. Western calendars are only based on the position of the sun. From the position of the sun and moon, five different attributes of time are calculated and displayed on the calendar.
What are the five attributes of time?
The five attributes of time are:
- tithi - the moon phase (half-waxing, quarter-waning). (personal relationships)
- vaar - the day (Monday, Tuesday, etc.). (health)
- nakshatra - the position of the moon in the zodiac. The zodiac has 12 signs which then are formed of 27 constellations. The nakshatra indicates the current constellation. (prana)
- yoga - the angular relationship between the sun and moon (getting along)
- karana - represents half of a tithi (work/karma)
How are the holidays calculated?
Currently, the holidays are a work in progress as they are all calculated from the sunrise tithi. Some holidays, such as shivaratri, need to be calculated from the night. Consult with your local pundit for any discrepancies.
